CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Provisional Application No. 62/660,715 filed Apr. 20, 2018, and the foregoing application is incorporated by reference herein in its entirety.

BACKGROUND

It is known in the art to provide greeting cards that are able to generate sound and/or pop up so-called 3 dimensional images. Typically the sound is generated by a small battery and computer chip that is embedded in the card that will produce sound and have an electrical connection when the card is opened by the recipient. New technology has evolved to the point where it can be used to improve upon the experience of the prior art sound and 3 dimensional popup cards.

Also known in the art is the use of conventional small note pads that are usually provided in a stack of removable, single sheets that also are provided with an adhesive substance along a portion of the backside of each sheet so that they may be written upon and attached to various surfaces and removed thereafter. A common example of these is Post-It notes. The principles described herein utilize thin screen technology that is incorporated into an electronic version of prior art note pads. In a preferred embodiment, the thin screen is incorporated into a module that mimics the physical dimensions of the prior art pads. The module can be provided with any number of attachment mechanisms on the backside so that it may be attached to a particular surface; e.g., the module may have a magnetic attachment means to position it on a refrigerator or other metallic surface, or it could be provided with a commercially available adhesive that is easily removable, such as those provided by The 3M Company, to attach it to other surfaces. The module with the incorporated front side screen is equipped with appropriate and well known microchips to allow the module to communicate over a network via communications standards such as WiFi and Bluetooth. Once connected, the user would use a website and/or mobile application to enter messages to be displayed on the screen, and other variables related to the messages, such as time and date, length, disposable, recurring, or link to other apps, such as an e-calendar. The messages would be saved on the module and the website/app. The reader of the messages at the site of the module could scroll through historic and saved messages through a small GUI on the screen, which is preferably touch screen enabled.

The principles described herein recognize that technology has now evolved to the point where video can now be displayed on screens or film that are thin enough such that they can be used in the manufacture of greeting cards. For example, thin and flexible OLED displays are available from companies such as Sony and LG. Other companies are developing their own versions of such screens using LED technology for certain applications, such as Apple's development of MicroLED technology. Although not yet commercially available, the principles described herein utilize such screen technology in several new products and services.

SUMMARY

In one example, a thin film video display is mounted onto card stock and incorporated into a greeting card and is powered by a small power source such as a conventional dime sized battery and activated when the recipient or other user unfolds the card. The activation mechanism is chosen from mechanisms known in the art, such as mechanisms typically used in prior art cards that produce sound effects.

In some embodiments, the card is supplied with prerecorded video and/or messages appropriate for the intended use of the card. For example, a birthday card could include a prerecorded message of a famous figure singing happy birthday, and a holiday card could include a snowfall or summer ocean scenes. If used in other media, the principles disclosed herein could be utilized for consumer information. For example, the technology can be incorporated into a menu to show highlights or photos or specials. It could be used in a promotional brochure or marketing package, such as those used by agencies and firms looking to attract employees or investors, to show a small video of appropriate promotional material in the brochure. The images that could be recorded and displayed are limitless.

If the information transferred from the computer chip inside the computer chip case 302 to the thin film video display 104 contains audio, the audio will be played out of the speaker 208 which is plugged into the audio jack 206 through the audio connector 210. In some embodiments, audio connector 210 is connected to chip data input/output port 404, thereby eliminating the need for audio jack 206 and allowing for the audio to be transmitted directly from the computer chip case 302 to speaker 208.

Greeting cards are often cherished by recipients and frequently looked at over time. While handwriting is somewhat permanent, a video screen will only be able to display video for the life cycle of its battery or power source. With further reference to FIG. 4, the battery inside computer chip case 302 is preferably positioned inside a coin cell battery holder and connected to computer chip by a wire, through direct contact, via a printed circuit board (PCB), or other suitable means. In some embodiments, the battery may be recharged by connecting an optional power source 314. The connection may be made via a standard electrical charging cable, such as a mini USB cable or other suitable connector, coupled to a suitable power source. The cable or other connector can be used to recharge an internal battery within the computer chip case. In some embodiments, the card 100 comprises a replaceable battery which may be accessed and replaced via a small slot in the computer chip case. A suitable battery, such as a commercially available coin battery, may be used for this purpose. In other embodiments, a thin-film battery may be utilized without departing from the principles disclosed herein. Further, in some embodiments, a wireless charging technology may be used, such as an induction charger that allows an internal battery to be charged wirelessly when the card is placed on a suitable charging base. The audiovisual message stored in the card is preferably stored in non-volatile memory so that it is not lost when the power source is depleted or disconnected from the device.

The thin film video display 104 can be used to display prerecorded text, images, or video from a known database or from a recorded message. For example, a user may choose a message from a prestored database, such as, for example, video clip sharing service YARN (available at https://getyarn.io), and select a prerecorded message to be downloaded to the card. In some embodiments, the thin film video device comprises a wireless modem coupled to the chip which enables wireless communication (such as Bluetooth and/or WiFi connections) between the card and nearby electronics device such as a mobile phone or computer. In some embodiments, the thin film video device comprises a wired communication port (such as a micro USB port) which enables a wired communication with an electronics device, such as computer or a kiosk at the location where the card is purchased. Instead of, or in addition to, using prerecorded media, a user can enter text and/or take a photograph and/or a video on a mobile phone or other recording device and download the media to the card through the aforementioned means of communication. Software may be required to format the data to meet the requirements of the chip and thin film display. If so, the user may download an application that enables the data to be formatted accordingly. The user may also upload the media to a website to have the data formatted accordingly and then download the formatted data for use on the card. The disclosed application and or website optionally enables the user to modify the media by, for example, adding filters or effects or additional text to the media before downloading it to the card.

In some embodiments, a card is supplied with prerecorded video or messages appropriate for the intended use of the card. For example, a birthday card could include a prerecorded message of a famous figure singing happy birthday, and a holiday card could include a snowfall or summer ocean scenes.

In accordance with the principles disclosed herein, a thin film video display can be used to create an electronic small display akin to a Post-It note. The display case or mechanism can be supplied with a removable tacky substance, such as 3M Commander, so that it can be displayed and/or moved to any location. In some embodiments, the display is be supplied with a magnetic backing that can be fixed to any appropriate surface. The display and micro controller can be accessed through a wireless connection through a website or mobile application so that the user can enter digital information such as messages, photographs, or video and can control the display and or management of the information from the website or application. In some embodiments, the device also has the ability to store messages and display them at a time specified by the user. If a user is away from the location of the device, the user can enter messages to be displayed on the device remotely and can control the time at which the message will be displayed. For example, a user can post a message to take out the garbage every Tuesday at 3:00 PM or take the dogs out at any time specified by the user. In some embodiments, the user can program the device locally, either through a wired or wireless connection, to store predetermined messages and/or schedule such messages to be displayed. The messages can be stored in the device, and the viewer of the device can have the ability to look at stored messages by using an icon or using swipe technology known in the art.

The principles disclosed herein may also be utilized in other media for consumer information. For example, the technology can be incorporated into a restaurant menu to display options for purchase and highlight certain items, list specials, or display photos. It could also be used in a promotional brochure or marketing package, such as those used by agencies and firms looking to attract employees or investors, to show a video of prerecorded promotional or marketing material.
